Variables associated with the hospitalization of psychiatric emergencies evaluated in the community.

We investigated hospitalization factors in acutely ill patients visited by psychiatrists at home. A series of 100 consecutive calls for psychiatric emergencies of a community mental health centre were investigated with a structured evaluation of psychiatric symptoms and aggressiveness (IEF, GAS, and VSAS). First order interactions were tested, and selected variables were tested with logistic regression analysis. Admission was significantly associated with GAS scores (low scores were found in 92.6% of admitted patients vs. 43.8% of patients not admitted), paranoid delusions (66.7 vs. 39.7%), and lack of social support (70.4 vs. 30.1%). Multivariate analysis confirmed a significant independent effect only for low GAS score and lack of social support. The study replicated some findings from research on hospitalization in emergency wards, while other factors, such as 'diagnosis' and 'suicide risk', were not significant.
